Projectile Motion
After observing the graph you could see, the position of the ball is persistently moving further away from the reference point (the foot). The velocity is constant which means the position/time increases by the same factor this means the trend shown in the position/time graph is linear. In the velocity/time graph velocity is constant because the ball is traveling at a constant rate. In the acceleration/time graph, there is no acceleration, as the ball is traveling at a constant velocity.
As you could see, the position of the ball from zero is slowly moving away from the reference point until it reaches it max height then the ball returns back to the reference point. The ball slows down as it moves away from the reference point because there is a vertical acceleration of -9.8m/s. The balls velocity at the max height is 0m/s. The reason the ball doesn’t come straight down from the max height is because the horizontally velocity is constant (No horizontal acceleration).
To achieve the maximize the range (horizontal displacement) of the soccer ball, it must be kick at a precise 45 degree angle.
